Pros On the road, works great for all PCS and Cellular carriers (800 MHz and 1900 MHz)
Cons Won't work outside the car and won't work when the signal is weaker than -120 dB.
Summary Wilson amplifiers are the best on the market and they do amplify your signal... as long as there is one. They also DO work on iDEN/Nextel and they have an iDEN High Power amplifier that rocks for iDEN/Nextel users... you just have to specify the frequency and carrier and order the right part number. Wilson has a full line of mobile and in-building amplifiers for your house, office, RV, boat, or vehicle.

Pros Works as advertised
Cons None for me, but maybe price for the thrifty shopper.
Summary I have a Wilson amplifier that was part of a kit I purchased in hopes of being able to use my cell phone in a slightly better than week signal area. I ordered it as a dual band so all of my friends and colleges could use their cell phones as well with out going outside of the building. The kit I ordered came with an outdoor antenna, the Wilson amp, a custom length of coble to connect the outside antenna and a repeater that mounted inside of the building. Before I mounted the outside antenna I found the side of the building with the strongest signal, 2 to 3 bars was the max. After installing the system I have a solid 2 to 3 bars on the phone using the phone inside.
It may seem like a lot to pay, but when you have to place your phone on a window sill in hopes that it will actually ring and then run outside and stand in the cold, or snow, or rain, or just plain go outside to talk on the phone, I would have to say that this thing was well worth the coin you pay.
My recommendation would be to find a dealer that cells the package that offers a system that does not rely on the cradle, but uses the inside repeater so you can move around the building or home and use your phone un-tethered.
Note that my rating may not be completely accurate because of the configuration that I use with the Wilson amp please read.
